Steelers look to jump start offense as they host Chargers again

San Diego's defense stood tough when threatened by the Pittsburgh Steelers in November. That's the type of resiliency that has given the Chargers a rematch.

Another ineffective effort on offense for the Steelers isn't likely to be good enough this time against the streaking Chargers, who have advanced to this AFC divisional playoff game Sunday at Heinz Field even though LaDainian Tomlinson is ailing.

After a bye week, AFC North champion Pittsburgh (12-4) will face San Diego (9-8) for the first time since a game that embodied all of its ongoing concerns on offense.

The Steelers beat the Chargers 11-10 at Heinz Field on Nov. 16, but did not score a touchdown despite making three trips inside San Diego's 20-yard line. One drive ended when Mewelde Moore was dropped for a 1-yard loss on fourth-and-goal from inside the 1, and Pittsburgh repeatedly hurt itself with 13 penalties.

"We moved the ball, but we sputtered in the red zone," Steelers quarterback Ben Roethlisberger said. "We can't afford to do that. We can't turn the ball over. The big thing is we can drive up and down the field, but we have to be able to put the ball in when we get down there."

It was the first of three straight losses that appeared to do in San Diego's playoff hopes, but it won its last four games and took the AFC West title after beating Denver in the regular-season finale. The Chargers went on to upset Indianapolis 23-17 in overtime in a wild-card matchup last Saturday.
